A mad tsar's evil jeep is apparently a
simulation
written in
Lisp 1.5,
running
on a network of
PDP-11/70s
connected via 3 Mb/s ethernet using
XNS protocols.
Recently it had his user-interface rewritten in
Tcl/Tk, and its sense of humor node was replaced
by mushi.taronga.com, a
486/33 running
FreeBSD 2.1.
